Influence of Nanopolymer Preparations Based on Chitosan Bombyx Mori on the Germination of Seeds of Wheat Varieties

In recent years, the introduction of nanotechnologies for use in grain growing has been widely spread. The effect of nanopolymer preparations based on chitosan on the laboratory germination of various wheat varieties Krasnodar-99, Oksuv, Dustlik, Semurug, Tezpishar and Istiklol-6 was carried out at the Research Institute of Breeding, Seed Production and Agricultural Technology of Cotton Growing in 2018-2020. The best indicators of laboratory germination had seeds treated with nanopreparations Nanoascorbatchitosan 0.5% (4:1), Polymer-metal complex Cu2+:Ag 8:2 and Nanochitosan 0.5% (90 kDa), which had a higher germination rate than the control and the Daltebu standard for all studied varieties of various origin. The influence of nanopreparations on the length of the aboveground and underground parts of seedlings of wheat varieties Krasnodar-99 and Grom was also studied under phytotron conditions on the 7th day, where the measurements of nanopolymer preparations in the Krasnodar-99 variety exceeded the control in the aerial part by 9.8-15.3mm, and underground at 11.3-17.5mm and standard at 4.9-9.4mm; 8.2-14.4mm, respectively. The same picture was observed in the Grom variety.
